Traditional lighting is focused on the prevention of hardware failures. With the trend toward controlled and connected systems, other components will start playing an equal role in the reliability of it. Here reliability need to be replaced by availability, and other modeling approaches are to be taken into account. Software reliability can only be covered by growth models, with the Goel-Okumoto as a promising candidate. System prognostics and health management is the next step to service the connected complex systems in the most effective way possible. In this chapter we highlight the next frontiers that will need to be taken in order to move the traditional lighting catastrophic failure thinking into a thinking more toward new ways how system (degraded) functions can fail or be compromised.@en

Highly Accelerated Lifetime Testing (HALT) and Multi-Environment Overstress Testing (MEOST) procedures are used to test the reliability of LED modules, drivers, and systems. HALT and MEOST are very useful test methods to assess the reliability of LED modules, drivers, and systems. However experiences are only recent and hardly any significant feedback from the market is received. For assessment of the driver reliability a main advantage is the structural similarity with many Switch Mode Power Supplies used for other, traditional, lighting applications. For LED module- and system-level constructions, design and materials used often are new. Many different system solutions exist and many will still be developed at an increasing speed. This implies a higher reliability risk for LED modules and systems. In this chapter, we describe our current results of HALT and MEOST procedures for LED modules, drivers, and systems.@en
